You are correct that skunk spray is a thiol, I just use the word terpene or terpenoid because that's the terminology everyone is familiar with as far as taste and smell these days. The big question is what combination of genes or cross is it that sets this whole thing free? The closest thing I grow that even resembles it is Chemdog D and she is my favorite smoke by far, perhaps line breeding to the D with a nordle, or devil male will eventually crack the code. Truth is, I don't care how it comes about, I just want it back desperately.
I think that this is going to be complex and secondary and not a simple matter of having genes that make the skunky thiols. As a slightly tangential bit of reasoning, the similarity in structure between grapefruit thiol and alpha-terpineol makes me wonder if terpenes (or perhaps terpene alcohols) may compete with other pathways, producing the fruity thiols over the pungent ones. The sulfur stuff in plants afaik is all from cleavage from the sulfur-containing amino acid-derived stuff.
I’m not into brewing, but you are very correct that it is a bounty of related information. Thiols in beer brewing are often inactivated, and require fermentation to become the free form that has the characteristic odor. So perhaps the modern methods of drying and curing the cannabis has changed. It’s also true that thiols are highly volatile, and most containers don’t contain them for long, but we all remember that the afghan skunk spray buds didn’t just loose their odor… but some research here might uncover something.
I find the Malawi Cobb curing to be a fascinating idea, one I’ve never done, for what that’s worth. But what if there is a fungal/bacterial aspect to the skunk smell? Perhaps, like beer, some microorganism unlocks the thiols, and some programs are not supporting those organisms or they have died in the environment. I don’t have any direct evidence of this but it’s interesting speculation.
